1.3.4.3.2.6.  Exact search {}

For an exact search, place the search term in curly brackets {}.

Condition: The searched term must appear in the result in exactly the same way. However, other terms may also appear in the result. The exact search does not tolerate Stemming or word splitting.

Example:

A search with

{Schraube}

will find "Screw" or "Lever with screw", but not "Screws" or "Screwdriver".

The syntax has been changed compared to V11.

Syntax in V11: exactdata=Bolt

Syntax in V12: {Bolt}

For a better understanding, two important differences between phrase search and exact search should be mentioned:

  • Stemming:[16]

    Phrase search:

    "mit gebördelt Rohr"

    finds "flared couplings" (stemming tolerated)

    Exact search:

    {mit gebördelt Rohr}

    does not find "with flared pipe" (Stemming not tolerated)

  • Compound words (mainly relevant in German):

    Phrase search:

    "Schraube mit Mutter"

    also finds "Zylinderschraube mit Mutter". (The compound word "Zylinderschraube" has been treated split in its subparts.)

    Exact search:

    {Schraube mit Mutter}

    does not find "cap screw with nut".
